The improved burglar alarm which Jl'oirn the subject niatter or' this application i adapted to be Avaried slightly in accordance with the position ot use and manner oit installation, but in general coinprises a traine composed ot' spaced and substantially' parallel side bars 50 connected by a plurality or spacing rods 5l, 52, 58, 51tand 55. yifhe rods 5l and 55 serve to clainp the side bars 50 upon the upwardly extending' arins of lil-shaped iiieinbers 56 and The arms 57 extend upwardly above the side bars 50 and are again preferably connected by a spacing' rod 38.

lilloiuitod upon the spa/idgl rod as a fulcrurn are a plurality of bell crank levers 59, 60 and 6l which are respectively vided with hoolrs 62, and

respectively by chains or cables repres diagraniinatically at 65, 66 and 6.7 it being' understood that repreeeiitiiigl ti vices as chains is only a convenient moans oi showing' and in no Way liniits fie invention. The connections 65, 66 and 6i' respectively connect With cables 66.. 69 TO which extend to openings or l; to be protected by the burglar clarin. fr `great variety of connections inaj,7 be einployf for such purposes as will be nore 'l'ully '.@iderstood at the description or the invention develops.

Preferably, there are interposed betweei the chains and the cables springs and .73 so that, When the. device is not use as, for instance, during the day the chains inay be transferred respect' troni their hooks 62, 63 or 64 to sta ary lioolrs 74e, 75 and 76, as indicatori dotted lines at and 66.

As shown and described, three oit i the levers 60 and 6l and their associated parts are disclosed. lt is to be understood that the invention .is in no limited this .nuinber and the nuinbe inay be r or less as occasion may inalre necessa or desirable and the showing tliroughrthe drawings o?? iiioie or less under any cuii'istance or conditionv is intended any variation of the inveiitici :is the invention includes any number o'i such levers :ind accessories as niay bc deterrniiied upon.

The several levers 59, 66 and 6l are iespectively pivotally connected With plungei's 7i, T5 and 76, such plungers ridingT upon a bail 77, leepers or clips 7S, 79 aY beingrigidly attached to said pluicczs the purpose or.' inaintainine` said p proper relation with the bail. keepers' also are employed it and when found desirable to carry aniiunciator plates 82 and 8E which carry numeral-s or er proper designating characters, pret'- erably radio active which, when properly dis layed through a` housing covering the device not shown, will indicate which one of the levers has been actuated by the cable.

The bail 77 is pivoted, as Will be noted, upon thc rod and is provided at one end with an extension lever 84 which is connected by iii-ans ot a pivoted linll: witha trigfrer 86 lulcriiined upon the rod 55.

Carried also by the rots 55 and :'38 are des 5l? properly spaced and rigidiied by loclr nuts or other Well linoivii niecliaiiical means and provided with aligned openings for the proper sliding action or" the liring pin @8 which is provided with a spring 89 which, when the tiring pin isreleased ln y case, a protector 95 is employed siinplyA to protect Walls, r'urniture or the like troni the action of the detonated charge. This protector is carried iii any approved inannel', as for instance upon the rod 58. The

iiriiig pin is provided with a detent 96,'

properly proportioned so that, when the tiring pin is turned, the detent 96 will engage upon the nut 97 to be thereby inaintainet in inactive position until forced out oil such engagement by the linger 96 ot trie trigger 86, which responds to each Inoveiiient of any of the plungers le, 75 or 76 acting),` upon tl e bail 77 through the li'l lr 85. lt follows, therefore, that., when the il 77 is moved by the niovernent oi any the plungers th-rcifgh the action o-'lf any the bell crank le rs, the deteiit 961 ot" 'rii'ig pin is dislodged troni its support uponv the nut 9i' and under the action t the 89 detoiiates the cartridge.

.For i l" .rpose ot properly limiting* the throw or inovenient olf the several levers 60 and 6l, a rod 99 properly positioned to be engaged said levers at their upward throw, lower lli nient beii y defined bjr the rod' 5s. for the levers, indie-Nel by the plates i160, are also employ-ad, the rco 99 being' prop` erly braced maintained rigid by the braces lOl.

Journaled also in bearings 102 is a shaft 103 subjected to a rotating stress, preferably` applied thereto by means of a cord or cable 104; placed under tension in any usual and ordinary manner as, for instance, by the spring 105, as shown at Figures et and: 5,-

or by a Weight 106 attached directly to said cable as shown at Figures 3, 8, 17 and 29, or a weight 107 connected to the cable 104 after passing over a pulley 108, as shown at Figures 16 and 38, or connected to other units as indicated by the cable 109, as shown at Figure 17, or 110 as shown at 'Figure 29 (Sheet 6).

This rotating shaft 103 is provided with any usual and ordinary attachment for ringing the bell 111 when the shaft is rotated. No particular novelty is claimed for Asuch mechanical means and any well known device for the purpose may be employed. At the end opposite the bell, the shaft 103 is provided with a plurality of radially eX- tending arms 112, here shown as four in number but it is to be understood that any greater or less number may be employed with equal or like effect. The bail 77 carries a finger 113, properly arranged to be engaged by one of the arms 112 when the bail is in inoperative position whereby the shaft 103 is held against rotation. `When, however, the bail is moved forwardly by any one of the Dlungers 74, or 76, the finger 113 is moved out of engagement with the arms 112 and the shaft 103 rotated by the stress applied thereto by the cable 104 ringing the bell.

' A complete alarm unit will, therefore, contain the mechanism hereinbefore described comprising the sounding alarm and ther detonating alarm. ln ordinary installation, this will be mounted upon a supporting structure represented by the legs 114 atl tion, the yoke 117 may be omitted.

At times and in certain positions, both the detonating and the sounding alarms are not found necessary, as for instance as shown at Figures 7 and 8, which discloses a simpler construction employed for local or temporary use. Also as shown at Figures 26 and 38, the detonating device may be employed in a plurality of numbers to be operated successively or as their connection may make necessary.

In the ordinary installation of the device, as for instance for the protection of an oc cupied residence, the cable 70 will run over the necessary pulleys 118, the position and arrangements of the pulleys depending upon the position of the unit and the relation of the closures to be connected therewith.` For the purpose ofvconnecting the several clos* ures, a shaft 119 is properly mounted in bearings 120, the positionof the shaft depending upon the type of closure to be protected. In any event, it is provided at one end with a lever 121 connected by means of a cord or cable 122 with means for rotating the shaft at the opening of the closure. These cords or cables 122 are connected directly with or, after passing over pulleys 123, to the cable 118, so that, when any of the cords or cables 122 are placed under stress by the opening of a closure, the cable 118 and connected cable 70 are likewise placed under stress, lifting the connected lever, in the case illustrated the lever 61 operating the bail and other devices as disclosed.

For connecting to the closure, a second lever 124 is connected to the shaft 119, preferably at an angle. This angular arrangement is accomplished in the manner shown at Figure 9 by employing multi-angular extremities upon the shaft 119 or by em-y ploying set screws as shown at 125 shown at Figure 25 (Sheet 7) or by any other usual and ordinary mechanical expedient. The lever 124 is actuated by a structure intervening between such lever and the opening member, as a door or a window. In the case of a window, the cable 122 may be provided with a hook 126 (see Figure 8, Sheet 5, or Figure 18, Sheet 7), such hook engaging a securing or similar member 127 in the lower sash. For the upper sash a lever 128 is pivoted as at 129 and connected at the end 130 with such upper sash, so that the lowering of the upper sash acts upon the hook 126 in the same manner as the `raising of the lower sash, In this position, preferably a guard plate 129 will be mounted upon the sash to obstruct a hand which might be inserted through the window upon the breaking of the glass for disconnecting the parts.

The connection with the door has been shown asv various forms at Figures 14 and 22, Sheet 5, and Figure 33, Sheet 9. 1t comprises a bracket 131 secured to the door 132 with an arm 133 pivoted thereto at 134. This arm 133 is provided with an extension. At Figure 14, this extension 135 is pivoted to the arm 133 at 136 and is provided with a plurality of spaced perforations 137 which, through the action of a cotter pin 138, connect directly with the lever 124. In case where it is desired to close the door afterl leaving the building, however, a plate 139 is riveted or otherwise secured to the lever 135, as shown at Figures 22 and 33, th-e saw teeth of this plate engaging a pin 140 carried by the lever 124. As shown at Figure 14, when the plate 139 is attached thereto,

Sii

finit lll) it may be moved laterally relative to the I lever 124 and, as shown at Figure 33, may be raised and lowered, a chain or other limiting means 141 being affixed thereto and to the door.

A device also which will enable the user Lif) Linen-1s 12', Sheet 5) connected by means of a back'et 1413 to the door 132 having a'v hook 1411" engaging selectively With the .links of a chain carried by the bracket 14?, To this a cable 146 is connected in the manner shown at Figure 5. This particular type of connection is designed more particularly for the protection of outbuildings and the cable 146 is carried through necessary hangers and Supporters 11-7 and enters the building equipped with the alarm unit.

To prevent the defeating of the purpose by cutting the cable, a bracket 118k is supporter Within the residence or other building, having a shaft 149 upon which is fulcrumed a plurality of bell crank levers 150 and 151. As shown at Figure 5, two of these bell crank levers are disclosed butv it is to be understood that the number may be more or' less as occasion may make desirable'. The cable 146 runs to the lever 150, and a spring 152 is employed to actuate the. lever 1510 when the tension on the cable 1416' is. released intentionally or being severed by an unauthorized person. The release of the cable 1416 causes the spring 152 to put the cable'69 under tension to actu-ate its attached lever, in this particular case thev lever 59.

The other bell crank lever here show'vn', 151, carries a cable 153 which passes over `a similar hanger 147 and is connected to" a cable 151V passing about Within the outbuilding guarded. The release of the cable 1541- will release the .cable 15B and the bell crank lever 151 will operate in the same manner described in regard to the bell crank 150. For `the purpose of releasing tension upon this cable, various means may 'be employed. At Figure 5, arms 155 and 156 are pivoted together at 157. This structure is shown in enlarged detail at Figures 10 and 11 (Sheet 5). A latch 158 is p-ivoted to one of the arms as 156 and is provided With a notch 1.59 which engages a pin 160 on' the other arm so that, when the arms are drawn together and latched as shown at Figure 10, the cable 154 is under tension. When the latch is released, the arms separate, as shown at Figure 11, whereby the tension upon, the cable 154- is released. To disengage this latch 156, a cable 161 runs to some release means. As shown at Figure 5, this releasing means is the shaft 119v and lever121. At Figure 6 (Sheet 4v), a plate 162 is fulcrumed at 163 over a key hole indicated in dot d lines at 164,v and the cable 161 extends over this plate and is connected by a hook165 with any convenient part of the `build-ing.

At Figure 32 (Sheet 9), a cable 1161 .runs first through a pulley 166 and is then Vengaged by a member 167 carried by a transom 168. 1 t its lower end', it is connected over the plate 162 as described. Either or both installations may be employed lseparately or combined.

s a further' means for releasing the tension' up'oir the cable 154, a knife 169 (see Figin-es and 30, Sheet 4) is fulcrumed upon a bracket 170,.- The bracket 170 is provided with a perforation 171 through which the cable 154 passes and a cable 17-2 extends to a lever' 121 or any other. meansV for exerting tension thereon when any closure is opened. rllhe tensioning of the cable 172 will, therefor-e, sever the cable 151 whereby the tension on said cable is released to operate the device as disclosed. To keep the cables 118 l and 154 under proper tension in view` oi:

varying' climatic conditions or the like, turn buckles 173" are employed as shown' at Fig-ure 5, Sheet 4.

The device installed as shown at Figurel 38 (Sheet 10) is intended more particularly for the protection of banks, store rooms or they like, which are unoccupied a considerable portion of the time and intended to give Warn-ing to the police or other persons upon the' exterior of the building. It comprises a plurality of detonating units only, as shown, mounted vertically upon braces 171 and provided with triggers 175 in the path of nio-vement of the Weight 107 sliding in the guideways 176'. Tubes or barrels 177 are provided connected directly with the detonating cartridge and extending outwardly through the side of the building represented at 178, so that the detonations may not only be hea-rd upon the exterior' of the building but the smoke resulting from such detonati'ons may be seen, or when desired the barrels may' be aimed to cover a given location and ball cartridges employed. The Weigh-t 107, as has been heretofore described, is connected with one of the alarm units, preferably in this case containing only the bell structure, the bell structure and detonati-ng structure being separated physically in this case but operating in conjunction. W'hen the arms 112 have been released by the pin 113 on the bail 77 in the usual manner, the Weight 107 through the medium of the cable 101` will' cause the shaft 103 to rotate to sound the ibe'll in theusual manner as hereinloefore described. The descent of the Weight 107 Will periodically engage each .of the several triggers 175, causing separate, distinct and spaced detonations. As shown in the drawings, three of ,tl'iese detonating devices have been connected to operate in conjunction with the bel-'l ringing unit, but it is to be under'- 'stood that a greater or less number of such .detonating devices may be similarly cmployed and operated by the descent of the yWeight 107.

In eases Where it is found desirable `or necessaryr to further protect the connection withy an oiitb'uilding to-` overcome craftiness -of burglars, a pneumatic device is employed. This comprises a cyli'nlerA 179 (see Figures and 37,- Sheet 10) having a piston 180 lill) mounted therein, connected 'with a piston rod 181 which in turn is connected with one of the plungers, designated as 50, but intend-ed to include any plunger employed upon the device be the same more or less. It is connected directly with the bail 77 in the usual manner. From this cylinder 179, a tube or pipe 182 extends, preferably under' ground, as indicated in dotted lines, and is connected with a storage tank 183 in which is stored compressed air. Air is admitted through the pipe 182 to the .cylinder 179 by means of a valve 1811 controlled by a cable 185 which in turn is controlled by the cable 118 extending about the building. The tensioning of the cable 185 serves to open the valve 1841, permitting the passage of compressed air from the tank 183 to the eylin der 179 to operate the device.

There has been shown at Figure 7, Sheet 5, a unit comprising the detonating section only secured to the wall adjacent the door 132. The connection with the door is or may be the same as hereinbefore described in which case, however, instead or' employing the lever 121 as shown, the said lever is provided with a finger 186 which engages directly upon the detent 96 of the firing pin 88. Substantially a like structure is shown at Figure 311 (Sheet 6) wherein a lever 187 is pivoted at 188 and is provided with a pin 189 extending overkthe path of the door operating the tiring pin in the manner described. y

As a further precautionary measure, the windows which are intended to be provided with the alarm may be covered with bars ot substantially the usual and ordinary type, as shown at 190 at Figure 19 (Sheet 7). The showing of this device in this ligure without the attaching means is merely tor clearness of illustration, the bars being upon the eX- terior, if desired, the connecting means, therefore, being upon the opposite side and not visible.

As a further guard to the window already or not protected by the connection as shown at Figure 8 (Sheet), a grid ot properconstruction, indicated as an entirety at 191, Figure`18 (Sheet 7) is mounted to cover the window. Preferably, this will be' mounted upon rollers 192 traveling` upon a track 193 and will be provided with Vmeans for engaging t'he inger 189 Aof the device corresponding` to the ltype shown at Figure. 34 (Sheet 6) so that, when the shaft 119 to which this is connected is operated by the swinging of the grid 191, the cable 19d will be placed under tension to unlatch the latch 158. To prevent the sliding oi' the grid instead of swinging action, a hook 195 iscarried by said grid engaging a pin or like structure 196.

This grid may be otherwise l.employed than. as. shown at Figure 18, as for instance las shown' at F igure31. 1n this case the hook is omitted and a cable 197 passes ov-er a pulley 198 so that, in case the grid is moved upon the track 193, the cable lis put under tension to exert stress upon the cable 118. As a further precaution, the grid is provid# ed outside o1 the lines of the window with a heavy bar 199 upon which are pivoted a plurality of bell crank levers 200, 201 and 202. springs 203, 204- and 205 and are connected by cables 206, .207 and 208 with the cable 197, a ring 209 formino a connection. The springs are maintained under tension and inoperative by nie-ans of wires 210 and 211.

which extend transversely across the grid or, preferably, by means of a heavy bar 212. This bar is employed in some instances as when manipulated by skilled burglar, Athe wires 210 or 211 might be held against re-v lease in some manner, but a heavy bar such as shown at 212 must ot necessity release its bell crank lever when severed.

As shown at Figure 26 (Sheet 8), the bars of the grid are, or at least may be, omitted and only wires such as 213, 2141 and 215 extend across the frame. In the particular installation shown, the detonating device is local, operated directly by springs 216, 217 and 218 controlling the detonating units 219 220 and 221. The severance of any one ot the wires will, therefore, cause its individual and separate detonation. 1n this vparticular embodiment, the rollers 192 are mounted in forks 222 so that the frame carrying the device may be removed from the track when desired by withdrawing the journal pins 223 and as easily replaced by' first moving the frame upwardly to embrace the track 193 in the forks and then placing the rollers 192 in position and the journal pins 223 in place.

1n some places and under some conditions, it is found inconvenient or undesirable to have the trame provided with the grid or the ,upper corners at 225 and a cord 226 passes over pulleys 227 as the mounting may make desirable and engaged upon a cleat 228 so that the frame may be drawn upwardly to or adjacent the ceiling, 'll he device tor producing the alarm shown at this igure is only intended as showing an operative device and the same construction may be employed with the grid as shown at Figure 18, orthe separate detonating elements asv shown at Figure 26.

Insome locations it is necessary to trans late motion in` one direction into motion in another direction. For that purpose aler r 229, as shown at Figure 21 (Sheet 7) is employed which may be at one end pushed by These are respectively controlled bya bar 230, exerting tension at its other end on a chain or cable 231. This is not intended for any specific connection with any speciic unit, but Wherever in the installation and operation of the device such translation ot motion is found necessary or desirable.

It is to be understood also that any oi the various connections, operating means and the like vvhich have been shown only in connection with certain other parts are not limited in their utility to such associa-tion but may be associated in any manner and with any of the several elements, units or parts which have been disclosed otherwise connected and associated.

The device is also capable of employment as a protection for automotive vehicles. At Figure 27 (Sheet 8) a conventional motor vehicle is shown having located therein at any convenient point, as under the cowl, a housing 232. The housing is provided with a cover 233', as shown at Figures 28 and 39 on the same sheet, with locking means indicated conventionally at 234. lWithin the housing as shown at Figure 28 a single detonating unit 235 is employed having a barrel or pipe curved to discharge without the lines of the car at 236. As shown at Figure 39,*tvvo of these detonating units are mounted in the housing and shown respectively at 237 and 238 with separate, distinct discharges 239 and r240. In the single unit device, a spring 241 is employed with a :able 242 extending to some vmovable part of the machineas one ofi-the rear Wheels 243. ln the double unit device, a similar spring is employed with a similar cable 242 similarly connected. The cable in this case is connected Within the housing to a lint: 945 which directly controls 'the trigger 86. For the second unit, a second trigger 8G is employed extending into the slot of said link, so that, When the cable 242-is relcasethtbe spring 244 iirst acts to ldischarge 'the unit '237 and the further movement of the link tuation, therefore, of any or' the plungers,

tating shaft is provided with a cable 25() Which is Wound thereon, extending to a lever 251 which in turn is adapted to actuate the bail of the second unit. The tivo units may be so proportioned that the detonation ot' 251, the cables may extend to second and third units, as shown at 252 at Figure 1T on said sheet, the first unit Winding the cable 252 and operating one of the regular levers to start and actuate the second unit which in turn Winds the cable 252 to start and actuate the third unit. As many of these units may be thus coupled as may be desired.4

It is believed that the operation of the several parts has been sutliciently described during the description of the construction of the Aunits and elements to be thoroughly understood in their various connections, interactions and 'functions and that a further description `would be superuous.
